[Claims for Utility Model Registration] A SECAM video signal generator that defines a video signal waveform as lines and segments, and selects and outputs preset waveforms for each line and segment. A line/segment generation unit that generates segment data; a frequency memory that receives the output of this line/segment generation unit; and a frequency memory that outputs frequency data corresponding to the line and segment; a waveform generator that outputs waveform data corresponding to the input; a gain memory that receives the output of the line segment generator and outputs gain data that corresponds to the bell filter; and a gain memory that outputs gain data that corresponds to the bell filter; a multiplier that multiplies these inputs, and a D that converts the output of this multiplier into an analog signal.
A SECAM characterized by having an A conversion section.
